Description

• eine Antriebseinheit zur Montage am oder im Möbelkorpus,
• zumindest einen bewegbar gelagerten Stellteil zum Bewegen des bewegbaren Möbelteiles.

The present invention relates to a furniture drive for moving a movably mounted furniture part relative to a furniture body, comprising:

• a drive unit for mounting on or in the furniture body,
• at least one movably mounted control part for moving the movable furniture part.

The invention further relates to a piece of furniture with at least one such furniture drive. Finally, the invention relates to a method for mounting a furniture drive on or in a furniture body.

Furniture drives that are positioned on or in a furniture body with the aid of a "ruler and pencil" are already known. A disadvantage of the known positioning measure, however, is that such positioning is only possible very imprecisely and with great effort. A correct assembly position is a necessary prerequisite so that the furniture part can be moved properly in the assembled state.

The DE 20 2013 007 519 U1 shows, for example, a mounting plate which is designed for fastening two or more actuators with housings of different designs.

The object of the invention is to avoid at least one of the disadvantages described above and to provide an improved furniture drive and an improved piece of furniture with at least one furniture drive, so that a simplified installation of the furniture drive on or in a furniture body is made possible.

Another object of the invention is to provide an improved method for mounting a furniture drive on or in a furniture body, in turn to ensure a simplified, in particular standardized, assembly.

These objects are achieved by the features of the independent claims 1, 11 and 12.

Advantageous embodiments of the invention are defined in the dependent claims.

An essential idea with regard to the furniture drive according to the invention is that at least one assembly stop that can be placed against the furniture body is provided on the drive unit. This measure enables the furniture drive to be positioned at a predetermined mounting position on or in a furniture body.

In other words, it can be provided that the furniture drive has at least one assembly stop that can be placed against one end of the furniture carcass, the drive unit being able to be positioned at a predetermined assembly position on or in the furniture carcass by the installation of the assembly stop against the front of the furniture carcass. The furniture body can have at least one vertically extending side wall, the end face of the furniture body preferably being formed by a vertically extending narrow side of this side wall. Alternatively, it can be provided that the end face is formed by a horizontally extending narrow side of a top wall of the furniture body.

According to one exemplary embodiment, it is provided that the drive unit has a housing and / or a mounting plate and that the mounting stop is designed as a component that is separate from the housing and / or from the mounting plate. This means that a damaged assembly stop can easily be replaced.

The assembly stop can be mounted so as to be movable relative to the drive unit. It is preferably provided that the assembly stop is mounted so as to be pivotable and / or displaceable relative to the drive unit between a first position and a second position.

According to a further exemplary embodiment, it is provided that the assembly stop is preassembled on the drive unit, the assembly stop being mounted on this drive unit so as to be pivotable and / or displaceable relative to the drive unit in the preassembled state.

According to a further exemplary embodiment, a cover cap can be provided, the cover cap at least partially covering the assembly stop in the first position and / or a lateral field of vision of the furniture drive in the assembled state. The cover cap can preferably have a curved section which is designed to cover the assembly stop in its first position.

In the case of a piece of furniture with at least one furniture drive, it can be provided that the piece of furniture has a furniture body and a furniture part that can be raised relative to the furniture body - preferably a flap - the furniture part being movably supported by the furniture drive between a closed position and a position raised relative to the furniture body. The movement of the furniture part relative to the furniture body is thus supported by the furniture drive, for example by a spring device and / or by an electric drive.

For the sake of simplicity, in the following, instead of the “housing and / or the mounting plate” of the drive unit, reference is made to a “mounting plate”, but the same statements apply to the housing.

Figure 1a shows a piece of furniture 16 which has a furniture body 3 and a furniture part 2 that can be moved upward relative to the furniture body 3. The movable furniture part 2 is designed as a furniture flap in this figure. Furthermore, a furniture drive 1 is arranged on each of the two side walls 9a, 9b, the furniture drives 1 each having a drive unit 4 and at least one movably mounted control part 5. The furniture part 2 can be moved by the control parts 5 between a closed position and a position raised relative to the furniture body 3. The furniture part 2 is in Figure 1 shown in a raised position. The actuating parts 5 can also have a multi-part structure. The furniture drive 1 arranged on the side wall 9b has, for example, three actuating arms 5a, 5b, 5c which are connected to one another in an articulated manner. In this context, it is also pointed out that the actuating parts 5 do not have to be directly connected to the furniture part 2. It an indirect connection via additional levers and / or fittings can also be provided.

Figure 1b shows a wall 9 and a section of a top wall 15 of a furniture body 3. The furniture drive 1 is not yet positioned at a predetermined assembly position. Furthermore, the furniture drive 1 has a drive unit 4, a movably mounted control part 5, an essentially T-shaped assembly stop 6 and two stops 6a. The assembly stop 6 is mounted so as to be movable relative to the drive unit 4. The two stops 6a serve to position the drive unit 4 in terms of height in the furniture body 3. The top wall 15 has an underside 14, the stops 6a being able to be placed against this underside 14 of the top wall 15.

Figure 2a shows a wall 9 and a section of a top wall 15 of a furniture body 3. The top wall 15 has an underside 14, and the two stops 6a can be placed against this underside 14. The furniture drive 1 again has a drive unit 4, an actuating part 5 mounted so as to be pivotable relative to the drive unit 4, an assembly stop 6 and the two aforementioned stops 6a. The essentially T-shaped assembly stop 6 is used to rest against the end face 8 of the wall 9. In contrast to FIG Figure 1b If the stop 6a shown on the left is already placed on the underside 14 of the top wall 15 and the drive unit 4 is thus pre-positioned in terms of height in the furniture body 3, the stop 6a shown on the right is then to be placed on the bottom 14 of the top wall 15.

Figure 2b shows the wall 9 and a section of the top wall 15 of the furniture carcass 3. The furniture drive 1 shown is now positioned at a predetermined mounting position on the wall 9 in the furniture carcass 3. The two stops 6 a, which serve to position the drive unit 4 in terms of height, lie against the underside 14 of the top wall 15. The assembly stop 6 is applied to the end face 8 of the wall 9 so that the Drive unit 4 is positioned in terms of depth in the furniture body 3. By placing a flat side of the drive unit 4 on the wall 9, the drive unit 4 is thus fixed in all directions in the furniture body 3 at a predetermined assembly position. In contrast to Figure 2a the assembly stop 6 is shown in a pivoted and displaced position so that the assembly stop 6 can be placed against the end face 8. As an alternative to this, it is also possible to place the drive unit 4 with a flat side on the underside 14 of the top wall 15, so that the assembly stop 6 can be placed on the end face 17 of the top wall 15.

Figure 2c shows the in Figure 2b circled area in an enlarged view. It can be seen that the assembly stop 6 has an axis of symmetry S, the assembly stop 6 being constructed mirror-symmetrically with respect to the axis of symmetry S, so that the assembly stop 6, by moving to the left or right, optionally on two different end faces 8, 8a of two opposing side walls 9a, 9b of the furniture body 3 can be applied. The furniture drive 1 shown can thus be positioned both on the left and on the right side walls 9a, 9b of a furniture body 3. In addition, the assembly stop 6 has the two stop surfaces 12, 12a arranged symmetrically to the axis of symmetry S. In Figure 2c the stop surface 12 is placed on the end face 8.

Figure 3a shows a perspective view of the furniture drive 1, the drive unit 4 comprising an assembly stop 6 which is movably supported by a bolt 10. In addition, the drive unit 4 has a mounting plate 7 which is used to fasten the drive unit 4 to a wall 9. Furthermore, a spring device 13 is provided for applying force to the actuating part 5.

Figure 3b shows the in Figure 3a circled area in an enlarged view. The two stop surfaces 12, 12a of the assembly stop 6 can be seen, these two stop surfaces 12, 12a serve to rest against the end faces 8, 8a of two opposite side walls 9a, 9b. Furthermore, the axis A can be seen, about which the assembly stop 6 is pivotably mounted. The drive unit 4 has a recess 20 for receiving the assembly stop 6. The assembly stop 6 has a first web 18 and a second web 19. The width of the first web 18 is less than the width of the recess 20 and the width of the second web 19 corresponds approximately to the width of the recess 20 possible after an at least partial pivoting movement of the assembly stop 6 relative to the drive unit 4. The actuating part 5 (not visible in this figure) is mounted so as to be pivotable relative to the drive unit 4 about the axis of rotation D, the axis of rotation D and the axis A running essentially parallel to one another. The direction R, in which the assembly stop 6 can be displaced, also runs parallel to the axis of rotation D.

Figure 4a shows the furniture drive 1 in a perspective view. In contrast to Figure 3a the assembly stop 6 is shown in a pivoted position. In addition, the mounting plate 7 can be seen, which is suitable for fastening the drive unit 4 to a wall 9 by means of screws or dowels (not shown).

Figure 4b shows a detailed representation of the Figure 4a . With regard to the axis of rotation D of the actuating part 5 and the direction R, refer to the description of FIG Figure 3b referenced. In addition, the recess 11 of the drive unit 4 can be seen, in which the assembly stop 6 in its first position according to FIG Figure 3a is at least partially absorbable.

Figure 5a shows the furniture drive 1 according to Figure 4a with a further position of the assembly stop 6, which in addition to the pivoted position of the Figure 4a is still shifted along the bolt 10 to the left.

Figure 5b shows the circled area of the Figure 5a in a different perspective view. So that the assembly stop 6 is held in a predetermined position in the second position, the assembly stop 6 has a flattened area 21. Another flattened area 21 is also formed symmetrically to the axis of symmetry S on the other side. As a result, the assembly stop 6 is also held in a predetermined position in the position shifted to the right along the bolt 10. In the position shifted to the left or to the right, the assembly stop 6 does not fall down under its own weight. The information "above" and "below" each refer to the usual mounting position of the furniture drive 1.

Figure 5c shows the detail area according to Figure 5b in another perspective view. The recess 11 can be seen, which is provided for at least partially receiving the assembly stop 6 in its first position.

Figure 6a shows a sectional view of the assembly stop 6 along the axis of symmetry S of the assembly stop 6. The assembly stop 6 is movably supported relative to the drive unit 4 via the bolt 10 and is in the first position in this figure. In addition, the axis A can be seen, about which the assembly stop 6 is pivotably mounted and can be displaced along this axis A.

Figure 6b shows the assembly stop 6 in contrast to Figure 6a in a position pivoted about the bolt 10.

Figure 6c and Figure 6d show the assembly stop 6 in a position displaced along the bolt 10. This position corresponds to the second position of the assembly stop 6. Furthermore, this position corresponds to the assembly state of the furniture drive 1, the drive unit 4 of the furniture drive 1 in this position in terms of both height and height can be positioned in terms of depth on or in the furniture body. These two figures also show that the in Figure 5b The illustrated flattened area 21 of the assembly stop 6 in the second position rests against the drive unit 4, at least in some areas, and the assembly stop 6 is prevented from falling down due to its own weight.

• Bewegen der Antriebseinheit 4 in eine Stellung, bis der Montageanschlag 6 an der Stirnseite 8 der Wand 9 des Möbelkorpus 3 anschlägt, sodass die Antriebseinheit 4 tiefenmäßig an einer vorgegebenen Montageposition im Möbelkorpus 3 positioniert wird,
• Befestigen der Antriebseinheit 4 an der vorgegebenen Montageposition im Möbelkorpus 3, vorzugsweise mittels Schrauben oder Dübeln (nicht dargestellt).

The inventive method for assembling the furniture drive 1 is based on the Figures 1b , 2a and 2b described. The following steps are carried out:

• Moving the drive unit 4 into a position until the assembly stop 6 strikes the end face 8 of the wall 9 of the furniture body 3, so that the drive unit 4 is positioned in terms of depth at a predetermined assembly position in the furniture body 3,
• Fasten the drive unit 4 at the specified mounting position in the furniture body 3, preferably by means of screws or dowels (not shown).

• Verschwenken und/oder Verschieben des Montageanschlages 6 relativ zur Antriebseinheit 4 in eine zweite Stellung, in welcher der Montageanschlag 6 quer von der Antriebseinheit 4 absteht, sodass der Montageanschlag 6 an eine Stirnseite 8 des Möbelkorpus 3 anlegbar ist.

Before moving the drive unit 4, the following step can be provided:

• Pivoting and / or shifting the assembly stop 6 relative to the drive unit 4 into a second position in which the assembly stop 6 protrudes transversely from the drive unit 4 so that the assembly stop 6 can be placed against an end face 8 of the furniture body 3.

• Verschwenken und/oder Verschieben des Montageanschlages 6 relativ zur Antriebseinheit 4 in eine erste Stellung, in welcher der Montageanschlag 6 in einer Ausnehmung 11 des Möbelantriebes 1 zumindest teilweise aufgenommen wird.

Furthermore, the following step can be provided before or after fastening the drive unit 4:

• Pivoting and / or displacement of the assembly stop 6 relative to the drive unit 4 into a first position in which the assembly stop 6 is at least partially received in a recess 11 of the furniture drive 1.

• Bewegen der Antriebseinheit 4 in eine Stellung, bis wenigstens einer der vom Montageanschlag 6 gesonderten Anschläge 6a der Antriebseinheit 4 an der Unterseite 14 der Deckwand 15 des Möbelkorpus 3 anschlagen, sodass die Antriebseinheit 4 höhenmäßig an einer vorgegebenen Montageposition im Möbelkorpus 3 positioniert wird.

The following step can be carried out before attaching the drive unit:

• Moving the drive unit 4 into a position until at least one of the stops 6a of the drive unit 4, which are separate from the assembly stop 6, strike the underside 14 of the top wall 15 of the furniture body 3, so that the drive unit 4 is positioned in terms of height at a predetermined assembly position in the furniture body 3.

At this point it is pointed out that it is not absolutely necessary to move the drive unit 4 for vertical positioning before moving the drive unit 4 for depth positioning. This can also be done in reverse order.

In order to facilitate the movement of the drive unit 4, the drive unit 4 can rest against the wall 9 of the furniture body 3 during the movement for positioning purposes and can be displaced along this wall 9.
